Embodiment Construction

[0029] One in figure 1 The hand-operated grinding machine tool 10 shown from the front side in the middle-a hand-operated superfinishing grinder-has a housing 12 whose upper area serves as a handle 13 and its lower area carries A grinding disc 14 that can be driven vibratingly by a motor, and a grinding disc 20 can be fixed on the bottom surface 18 of the grinding disc. Here, the grinding disc 20 is wound around the front and rear edges 15 and 17 of the grinding disc 14 with its two opposite grinding disc ends 21. Here, the ends 21 of the grinding discs respectively extend into the middle of the grinding disc 14 parallel to the upper side 16 of the grinding disc. The grinding disc end 21 can be tightly clamped between a supporting surface 22 on the upper side 16 and the clamping roller 24. The clamping roller 24 can be pivoted by means of a clamping lever 30. The clamping lever 30 is bent 90° from the clamping roller 24 and extends parallel to the longitudinal extension direction...

Abstract

The invention relates to a hand sanding tool (10) with a sanding sheet (20), covering the underside (18) of the sanding plate and with clamping means (22, 24, 30), for fixing the sanding sheet (20) to the sanding plate (14), whereby the clamping means (22, 24, 30) comprise clamping bodies (24), pressing on the ends (21) of the sanding sheet, characterised in that the clamping body may be freely rotated about an eccentric axis (28) and the pivot axis (28) is arranged essentially perpendicularly above a concave curved retaining surface (22).

Description

Technical field [0001] The invention relates to a hand-operated grinding machine tool according to the preamble of claim 1. Background technique [0002] In GB-Patent Application 232 2582, a hand-operated grinding machine tool with a motor drive is disclosed. It is provided with a tool for clamping and tensioning a grinding plate that can be held on the bottom surface of the grinding disc. system. The system works reliably and can operate well, but the tensioning effect on the grinding disc is relatively limited, so that the sensible relative movement between the grinding disc and the grinding disc cannot be ruled out. Summary of the invention [0003] The present invention with the features of claim 1 has its advantages, namely, to provide a hand-operated grinding machine tool at a reasonable cost, which can realize the efficient clamping of the grinding disc on the grinding disc and the simultaneous Effective tensioning, wherein the relative movement between the grinding disc ...
